Does charming an enemy Green Yasuo into a Battlefield during your turn trigger his attack ability?

Ruling: Yes, charming an enemy Yasuo into a Battlefield triggers his attack ability because the Yasuo is attacking.

Nuances:

• Yasuo's ability requires him to be "here" (at the location) when it resolves. If Yasuo is pushed back to base after the attack trigger goes on chain but before it resolves, his ability will not deal damage because he is no longer at that location.
